• Writes the processed data to JSON and CSV files
• Prepares the data for Google Sheets

Development

The project is written in TypeScript and uses the Google Sheets API to write data to Google Sheets. It also uses the d3-dsv library to format the data as CSV, and dayjs for date and time manipulation.

The main script is src/ts/index.ts, which fetches the data, processes it, and writes it. The data processing is done in src/ts/prepData.ts, and the writing is done in src/ts/writeData.ts).

You can debug the script using the configuration provided in .vscode/launch.json.
